Fellow Freelancers, how exactly do you get a client's website into their hands?

So I'm kinda at a crossroads right now. Well, I'm actually confused. So I'm set and ready to go to start selling websites on Fiverr, however, I am confused as to how I am supposed to deliver the finished projects. Ideally, I would like to be able to develop the websites on my end (hosting wise) and then transfer it over to the client's own hosting service, however, I don't know how to do that or if it is even ideal. I would just like to know the best strategy for delivering finished websites to clients, basically. Thanks in advance for any helpful advice.
